실험 절차
0.69 g, of 5-iodo vaniline, 0.5 g N-3-phenyl-n-propyl cyanoacetamide and 50 mg β-alanine in 30 ml ethanol were refluxed 5 hours. Evaporation gave an oil which was triturated with benzene-hexane and filtered to give 3-(4-hydroxyl-3-iodo-5-methoxyphenyl-2[(3-phenyl-n-propyl)aminocarbonyl acrylnitrile as a bright yellow solid (0.82 g, 71% yield, mp—83° C.). (3-methoxy 4 hydroxy 5-iodo α-cis cinnamone (3′phenyl propane)amide). (Should be kept solid and protected from light.
